Public domain offering. I made this in Photoshop and Windows Movie Maker.
This started as a NASA photo of the crab nebulae. I kept duplicating it and filtering it so it expanded out in a blur of dots. The original photo came from wikimedia commons. It is in the public domain.
You can use it with no worries about copyright infringement. It's free for everyone's use. Creating these clips is my way of thanking others who have contributed to the public domain. Sorry, but Windows Movie Maker file is all I have to create it in. Please enjoy its use and leave a review if you use it in a video. If interest is strong enough I will continue to create these files.
